Specification of Letters Patent.

Patented Aug. 1, 1905.

To CLZZ 7.0700711, z'f 'may con/007177,:

Be it known that I, LAFAYETTE S. SCOTT, a citizen of the United States, residing at 69 New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Cash-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention .relates to cash-registers of the spring-impelled type wherein the indicating mechanism is set to normal or zero point after the amount of each purchase has been indicated or registered and before the keys in each vertical row or bank can be operated to indicate or register another purchase.

One of the principal objects of the invention is to so construct a machine of this character that when a key is depressed the indicating mechanism will be directly set in motion without the manual actuation of an auX- iliary part and in which the particular singular depression of but one key in each row or bank will effect the actuation of the indicating device which it controls, so as to present the desired indication or registration immediately.

Other objects of the invention will become apparent upon a more detailed description thereof.

.The invention consists generally of the novel construction and peculiar arrangement of the several parts, as will be hereinafter more fully described, and briefly stated in the claims.

In the drawings, Figure 1 is an elevation, partly in section, of one side of a cash-register embodying the principle of my invention. Fig. 2 is an enlarged side elevation of a part of the escapement and registering mechanisms; Fig. 3, an edge view of the escapment-wheel; Figs. 4 and side views of the respective segment-slides forming a part of the escapement mechanism; Figs. 6 and 7, side and edge views, respectively, of one of the retainingpawls; Fig. 8, an enlarged side elevation of one bank or vertical rows of keys opposite to that of Fig. 1, showing the stop-arm and the segment-slides, partly in full and partly in dotted lines; Fig. 9, a rear view of the mechanism represented in Fig. 8; Figs. 10 and 11 and 19., 'detail views showing the operation of a key on the segment-slides; Fig. 13, a perspective View of a portion of one train of the indicating mechanism; Fig. 14, a detail view i of the connection between the segment-slides, West One Hundred and Eighteenth street, l

showing the normal position of the slotted trigger; Fig. 15, a perspective detail view of the operating-cam and one of the segmentslides, and Fig. 16 an edge view of a portion of the registering mechanism shown in Fig. 2.

As the present invention relates principally to the escapement mechanism operated by the keys, which operation is the same in each set of bank of keys, I do not deem it essential to a clear understanding of the invention to either illustrate or describe the registering mechanism, only so far as may be necessary to show the complete operation of a train of mechanism which produces the desired rotation of the indicator, as such registering mechanism is fully described and shown in Letters Patent, numbered 644,304, granted to -me February 27, 1900, it being understood that there are four banks or vertical rows of keysr and four trains of mechanisms precisely the same.

In the several views the numeral 1 indicates a spring-impelled indicator loosely mounted on a stationary shaft 2, iixed in bearings in the respective sides'of the frame. Secured to the hub of the indicator is a pinion 3, meshing with a toothed sector 4, which imparts motion, derived from the spring-impelled indicator, to a pinion 5, secured to a pawl-carrying arm 6, mounted loosely on a resettingshaft 7, said pawl-carrying arm having at its outer end a pivoted spring-actuated pawl 8, as shown in Fig. 13, for the purpose of engaging lugs or projections 9 on the side of an escapement-wheel l0, mounted loosely onthe resetting shaft. The escapement-wheel is held against rotation in one direction by a spring-restrained pawl 11, as shown in Fig. 1, and is provided with teeth 12, forming stops for the pallets 13 and 14 of an escapement-lever 15, rockably secured on ashaft 16, said lever being normally restrained by a spring 17, as shown in Fig. 2. Mounted on the shaft 16 is a rockable arm 18, provided with an upwardly -projecting pawl 18l and with a spring-actuated pawl 182, the pawl 18 being adapted to engage the teeth of a starwlieel 19, mounted on a shaft 20, and the pawl 182 being adapted to hold the star-wheel against forward movement when the rockable arm is in its upper position.

When the register is in its normal or at rest position, one of the teeth of the escapementwheel rests against the pallet 13 of the escapement-lever, as shown in full lines in Fig. 1, thereby preventing the indicator from rotating until said pallet is withdrawn from engagement with said tooth, which is accomplished b y the downward movement of the rockable arm 18, the escapement-lever being' connected with said rockable arm. As the pallet 13 is withdrawn from engagement with the tooth of the escapement-wheel the pallet 14 is forced upward and the beveled or inclined surface c, coming in contact with the beveled surface I) on one of the teeth of said escapementwheel, said wheel is permitted to rotate until the next tooth contacts with the straight face c of the escapement-lever. After the pallet 14 has permitted the escapement-wheel torotate one tooth the pallet 13 returns upward and the operation is repeated, the spring-restrained pawl 11 always acting to prevent backward rotation of said escapement-wheel. 1t will thus be seen that the escapement-wheel makes two stops in registering` a number and that the beveled faces of the teeth and pallets are employed to regulate its forward movement in unison with the spring controlling` the indicator.

As previously stated, there are four banks or vertical rows of keys in the complete machine, each bank containing' nine keys, and each key is provided with a spring' for returning it to normal position after it has been released from its depressed position.

The numeral 21 indicates a number of spring-actuated keys, which may be of any approved construction, having square shanks or stems, and each key is provided at its lower end with a pin 22, passingtransversely therethrough, one of the laterally-projecting ends 23 being' circular and the other 25 being semicircular in cross-section, as shown in Fig. 12. The pin end 23 is adapted to engage the inclined or beveled edges ofslots (Zin a segmentslide 24 and the end 25 to engage the slots in a segment-slide 26. It will be noted that the inclined edges of the slots CZ of the slide 24 vary in length, as shown in Fig. 4, for a purpose to be hereinafter explained.

rlhe segment-slides are mounted in guideways made in brackets 27 27, projecting from the key-bank frame, as shown in Figs. 1, 8,

and 9, and have a slight reciprocatory move-v The slide 24 1s provided withment therein. a pin 31, adapted to operate in a slot 32 of a trigger' 33, pivoted between ears 33', secured to the rear side of the key-bank frame, as shown in Fig. 8. The upper end of the trigger is provided with a hooked end adapted to engage a pin 34, projecting from the inner face of the segment-slide 26, as shown in Fig. 9, and hold said slide until the trigger is rocked out of engagement with the pin 34 by the downward movement of the slide 24 when operated by a key. One of the edges of each slot e ol' the segment-slide 26 is provided with a slight projection or ledge 34' and the lower edge with a recess 35, the ledge 34' being' for the purpose of preventing the withdrawal of a key after the first or initial upward movement of the slide 26 and the recess 35 for the purpose of locking said key against its return to normal position until the resetting operation.

Pivoted to a bracket 23, projecting from one side of the key-bank frame and connected to the slide 24 by a pin 28', is a rockable stoppawl 29, normally restrained by a spring 30, as shown in Fig. 3.

Mounted on astationary shaft 36 is a springrestrained rockable trip 37, provided with a laterally-extending lug 38, adapted to encounter a similarly-extending lug 39 on the segment-slide 26, as shown in Figs. 2 and 3. The roeka ble trip is provided with a pin 46, which overlies a retaining-pawl 41, mounted on the shaft 36, as shown in Fig. 2, said pawl being adapted to enter a notch 42 in the periphery of a disk 43, mounted on the shaft 2O and adapted to rotate with the star-wheel 19. Also mounted on the shaft 20 between the starwheel and disk 43 is a stop-disk 43', having its periphery provided with a number of graduated or stepped stops 44, which are adapted to be engaged by the stop-pawl 29 to limit the extent of rotation of the disk 43, disk 43', and the star-wheel.

The operation of the above-described mechanism is as follows: W'hen a key is depressed, the pin end 23 engages the inclined or beveled edge of a slot (Z of the segment-slide 24 (see Fig. 4) and forces said slide downward against the pressure of the spring 45 until said pin end enters the straight portion of the slot. As the slide 24 is being forced downward by the pin end 23 the pin end 25 enters the slot e of the segment-slide 26, past the ledge 34', and into the recess 35, allowing said slide to move slightly upward by the force of the spring 45'. As the slide 24 continues to move downward the stop-pawl 29 is rocked forward, by reason of its connection with the lower end of said slide, to a position to be engaged by the stop on the disk 43', corresponding to the number' on the key depressed, the

extent of forward movement of said stop-` pawl depending upon the length of the inclined or beveled edges of the slot (Z. The greater the length of incline the greater will be the extent of the downward movement of the slide 24, and consequently the greater the extent of forward rocking movement of said stop-pawl, as is evident. As the slide 24 continues its downward movement the pin 31, traveling in the slot 32 of the pivoted trigger 33, causes said trigger to rock backward out of engagement with the pin 34 on the slide 26, releasing said slide and permitting it to move upward under the pressure of its spring until the pin end 23 of the key has reached the straight portion of the slot d. At the time the trigger 33 begins its backward rocking movement the projection or ledge 34' of the slot c in the segment-slide 26 engages the pin end 25 of the key, thereby preventing' said key from being withdrawn until it has been depressed the entire distance and the register returned to Zero or normal.

. Vhen the key reaches its limit of movement,

the slide 26 moves upward under the force of pressure exerted by spring' 45 the instant pin end 25 enters the recess 35 of said slide. This movement of the slide 26 is permitted by the operation of pin 31 `in the slot 32 of the trigger 33, which inits downward movement with the slide 24 rocks said trigger out of engagement with the pin 34 on the slide 26, leaving said slide free to the action of the spring' 45. As the slide 26 moves upward the lug 39, extending laterally therefrom, is carried out of contact with the lug 33 on the side of the rockable trip 37, permitting said trip to rock inward and cause the pin 40, overlying the retaining-pawl 41, to force said pawl backward out of engagement with the notch 42 of the disk 43', thereby allowing said disk, the stop-disk 43, and the star-wheel to rotate until the stop 44,-corresponding to the number on the key depressed, is 'engaged by the stop-pawl 29. It will be noted that lug 39 remains in contact with lng 33 until the key is locked, because the slide 26 cannot travel upward until the end of pin 22 enters the recess 35 of the slot c. Wvhen the free end of the stop-pawl 29 engages one of the stops 44, the rotation of the disk 43, disk 43', and star-wheel is at once arrested, thereby limiting the number of escapements of the arm 13, which in turn governs the degree of rotation of the register-wheel 10. Thus it will be seen that the number of indications on the wheel 10 are limited to correspond with that of the key depressed.y As the starwheel19 rotates the teeth come in contact with the spring-actuated pawl 132, rocking the arm 13 downward, and thereby causing the pawl 13/ to enter between two of the teeth of the star-wheel to prevent the forward motion of the said wheel until the arm 13 has been returned to its normal position. This movement permits the indicator to register 1, and it will continue to register an additional "17 for each of the teeth of the starwheel that passes pawl 132.

The numeral 46 indicates a spring-actuated resetting-lever mounted at one end on a shaft 47 and having' its front end beveled, as shown in Figs. 1 and 14, to correspond with the beveled slotted end 43 of a push-rod 49, so that when said push-rod is pressed inward the free end of the lever 46 must necessarily move downward, the stem of the push-button being provided with'a spring similar to that shown coiled around the shank of the keys 21 to return it to normal position, and thereby leave the lever 46 free to return to its normal position after having been operated by the push-rod. Mounted on shaft 52 is a rearwardly-eXtending arm 51, (shown in dotted lines in Fig. 1,) carrying a pin 50, lying under the resetting-lever 46, whereby the said resetting-lever is returned to normal position by the spring-controlled' shaft 52. Mounted on the shaft 47 is a spring-actuated release-lever 53, to which is attached one end of a link 54, the other end of said link being attached to a hood or blind 55. The free end of the release-lever is provided with a notch 56, adapted to be engaged by a spring-actuated rocker-foot 57, pivoted on the shaft 52. Secured lon a shaft 53 is a lever'59 and a spring-pressed pawl 60, there being one of said spring-pressed pawls for each bank of keys. The lever 59 is provided with a pin 61, arranged to be engaged by the releaselever on its upward movement, and the shaft 53 is provided with a pin 62, which passes through an elongated hole or slot in the pawlsleeve, so that as the shaft 53 is rocked forward by the upward movement of the lever 59, which is raised by the upward movement of the release-lever 53, the pawl 60 will rock with said shaft to lock the remaining or unused keys in the bank. The pin 34 on the segment-slide 26is so situated that in an unused bank the pawl 60 will drop over said pin and hold said slide in its downward position, thereby preventing any registration taking place. Injury to the pawl 60 is prevented by the elongated hole or slot through which the pin 62 passes.

The operation of the resetting mechanism is as follows: When push-rod 49 is operated, its beveled end acting upon the beveled end of the resetting-lever forces the free end of said lever downward, and with itthe pin 50, which is carried by the arm 51, causing the shaft 52 to rock the rocker-foot 57 out of engagement with the free end of the releaselever, thereby permitting said release-lever to move upward and raise the blind or hood by means of the link 54 to expose to view the amount registered upon the indicator or indicators. In its upward movement the release-lever comes in contact with pin 61 of lever 59, and raising the free end of said lever causes the shaft 53, on which the lever is mounted, to rock the pawls 60 (only one shown) forward to lock the unused banks of keys, as heretofore explained; but in the bank of keys in which onekey is depressed the inner edge of the pawl comes in contact with the pin 34 and standing off allows the shaft 53 to carry the other pawls forward and over the pins 34 and lock the keys in the remaining banks not used. As soon as the push-rod is relieved of the pressure required to push it in the torce of the spring returns it to normal position, leaving the resetting-lever tree to retnrn to its normal position, after which a suitable crank secured on the resetting-shaft 66 is operated to reset the indicators to Zero or normal position. The keys, it will be noted, are released by the operation ot' the cam G23, secured on the shaft 20, whose edge 64 engages the curved projection 65 of the slide 9.6 and lorcing said `slide downward frees the end 25 of pin 22 from its engagement with the recess 35, allowing the key to bc returned to normal position by the action et" its spring. The cam 63 also resets the trip 37 by engaging' its tree end and forcingisaid end backward from its inward-rocked position on the shaft 20. i

Having thus fully described my invention, what l claim, and desire to secure by Letters Patent, is#- l. 1n a cash-register, the combination with a push-key, of a vertically-rcciprocatory slide adapted to be operated by the push-key, a second vertically-rcciprocatory slide adapted to lock said key, said slides being mounted in guideways and a connection between the two slides, whereby the operation of the key-operated slide will cause the operation oli the locking-slide.
